I just took a 220 gal to B & I (now called Bow Valley Aquariums). We just moved here from out East, and the tank unfortunately sprung a leak and then actually broke the seal! Anyway, it was a rush deal as I had the fish to keep alive, and they did a great job. They do come across as kind of disorganized, but they did a really impressive job on the tank, replacing the front piece with a new starfire glass piece. They completely tore it down, stripped all the sealant, resealed it with the new glass, and put in new side pieces, top and euro bracing. I wanted to keep my background attached to the back, as it took so long to build, and they accomodated that as well. I would not hesitate to recommend their workmanship, as long as you are patient.
